Whisper
The most widely used model for turning speech into text, covering more than 99 languages - for dictation, client conversations and meeting recordings. It produces a transcript, not an assessment of what was said; it does not detect speaker changes by itself, and during longer silences it can invent text, which is why transcripts have to be listened back against. On three of our routes the contractual chain is closed: on your own hardware, where no third party participates, in dedicated operation on reserved hardware, and via Azure, where the confidentiality undertaking under section 203 of the German Criminal Code is signed. The Open Telekom Cloud also offers the model, under its own standard agreement with its customers. For dictation the abuse monitoring active in the delivered state has to be considered as well.
Everything section 203 requires is settled, including the provider's confidentiality undertaking, and nothing is stored at the provider, apart from a technical cache of a few minutes for Claude (zero retention). You do not have to clarify anything further.
What it is good for
- MIT licence and small enough to run alongside on any dedicated instance
- More than 99 languages, robust even with background noise and telephone quality
- In production use for years - the most mature model in this class
Where it stops
- Does not detect speaker changes by itself - attribution in a multi-party conversation needs a second step
- Tends to invent text during silence or unintelligible passages; transcripts have to be listened back against
- No real-time streaming output - the recording is processed as a whole
Status through us
The same model, procured differently, is a different legal position. The status above refers to procurement through us; processing takes place in Germany.
Which route carries it, with which instrument and under which condition, we set out in full to the firm before it commissions us - section 203(4) requires that the chain can be checked, not that it is published. The full matrix, with the sources behind every route, can be requested in the German catalogue after confirming your e-mail address, and we go through it in the conversation.
Is Whisper the right fit?
We go through your tasks and the route that carries them - and say plainly where it does not.
